From: Increased ventilation by fish leads to a higher risk of parasitism
Relationship between the number of acquired Diplostomum pseudospathaceum metacercariae and ventilation activity in Oncorhynchus mykiss at three levels of oxygen concentration. A: number of metacercariae vs ventilation amplitude. B: number of metacercariae vs operculum beat rate. C: number of metacercariae vs ventilation volume. Squares – 30%, triangles – 60%, circles – 90% oxygen concentration.
